No. 213,316 1 Claim. (Cl.29259) The invention disclosed in the following specification and claimrelates to a tool for use in the repair of automobiles. Specifically,the embodiment disclosed is a tool for compressing a portion of astarter of an automobile so that the starter may be disassembled andrepaired.

Many tools for the compression of resilient members for repair purposeshave heretofore been proposed. However, so far as I am aware, none ofthese prior proposed compressors are satisfactory in the compression ofstarter assemblies. This is mainly for the reason that the starterspring of many automobiles such as for example, the Ford, Mercury, andLincoln automobiles, is enclosed in a rigid casing. Therefore it isdiflicult to design a compressor which will contact and compress theresilient member so that holding pins, etc. may be removed todisassemble the various parts.

Objects One of the objects of my invention therefore is the provision ofa new tool for the repair of automobiles.

A further object of my invention is the provision of a new compressorfor starter assemblies for automobiles.

Further objects and features of my invention will be apparent from thefollowing specification and claim when considered in connection with theaccompanying drawings illustrating an embodiment of my invention.

In the drawings:

FIG. 1 is a view in perspective of a tool constructed in accordance withmy invention;

FIG. 2 is a view in vertical section of the tool and of a starterassembly of an automobile to which the tool, similar to the tool shownin FIG. 1, has been applied for the purpose of compressing the assemblyand disassembling the starter and the parts associated therewith, partsof the starter being broken away; and

FIG. 3 is a fragmentary view similar to FIG. 2 but having additionalparts broken away and having the assembly shown in its compressedcondition.

Detailed Description It may be seen that I have shown in FIG. 1 acompressor generally designated consisting of a U-shaped frame elementor yoke 11, having a relatively heavy block 13 securely fastened at thebase 12 of the U of the frame and having (at the ends of the legs of theU) retroversions 14 and 15. The base 12 of the U, as well as the block13, are threaded for the reception of a threaded rod 16. The rod 16 isformed at its rear end with a handle 17 and adjacent to its forward endwith a cross piece 18. The cross piece 18 is slotted as at 21 and 22 toembrace the legs of the U member 11, and has secured to it a cup member23 formed with elongated cut-out portions 24 and 25.

As shown in FIG. 2, the starter assembly 31 includes a rigid casing 32within which there is a resilient member 33 normally held partiallycompressed between the casing 32 and the plate 34. The starter assembly31 also includes shafts 35 and 36. The shaft 35, adjacent its rearwardend, is formed with a hole for a pin 37. Shaft 35 is also formedPatented Aug. 4., 1964 with a collar 38. When the assembly is inoperation, the plate 34 bears against the collar 38. The rear end of thecasing 32 bears on the pin 37. Thus the member 33 is held in partiallycompressed condition between the pin 37 and the collar 38.

Operation In the operation of my tool the screw 16 is rotated (in thedirection opposite to the arrow) by the handle 17 so as to withdraw thecross piece 18 and the cup 23 toward the block 13. Thereupon the forwardend of the tool may be slid over the frame 32. A slight pulling back ofthe tool 10 (i.e. to the left in the drawing) causes the retrovertedportions 14 and 15 to contact the plate 34.

Thereupon the screw 16 is rotated in the direction of the arrow to moveit forward in the yoke or U member 11, until the cup 23 contacts theframe 32. The cup 23 is positioned so that the ends of the pins areembraced by the elongated cut-out portions 24 and 25. The tool is now inthe position shown in FIG. 2. Further rotation of the screw 16 by thehandle 17 causes the retroverted portions 14 and 15 to move the plate 34towards the rear of the frame 32 thus compressing the member 33. Thisreleases the pin 37 from its clamped position bearing on the frame 32,and the pin 37 may be easily removed.

Rotating the screw in the opposite direction now re leases the frame 32and it may be removed from its secured position on the shaft 35, and themember 33 also removed. The parts may now be completely disassembled andworn or broken parts replaced and the assembly repaired.

The assembling of the parts is of course the reverse of the operationjust described. The new or repaired resilient member is put in place ofthe member 33 and the new casing 32, or repaired casing, if repair isnecessary, is put in place of the casing 32. The tool is then applied inthe same way as previously described and the member 33 is compressed.The pin 37 is re-inserted and the assembly is complete. The compressoris then released and removed from the assembly.

It is to be understood that the above described embodiment of myinvention is for the purpose of illustration only and various changesmay be made therein without departing from the spirit and scope of myinvention.

I claim:

A tool for the assembly and disassembly of starter assemblies ofautomobiles wherein the starter assembly has a cup shaped casing, aresilient member in the casing, a plate also in the casing bearing onsaid resilient member, and a pin bearing on the rear of said cup shapedcasing and holding the resilient member compressed against the platecomprising a U-shaped member having a forward end and a rear end; formedwith a base at the rear end; having a threaded block secured within thebase of the U- shaped member; having a pair of retrograded portions atthe forward end of the U-shaped member;

a screw threaded through the threaded bore of the block member;

a handle for the screw;

a slotted cross member secured to the screw adjacent the forward end ofthe screw and formed with slots which embrace the legs of the U-shapedmember;

a cup shaped member formed with a pair of semi circular cut-out portionssecured to the screw adjacent to the forward end of the screw, the cupshaped member being provided for contacting the base of 'the frame ofthe starter assembly;

the retrograded end portions of the U-shaped member being provided forthe purpose of contacting the plate on the starter assembly within theconfines of 5 the casing of said assembly and for urging the plate ofthe starter assembly rearwardly to compress the resilient member of thestarter assembly and the cut-out portions of the cup being provided forthe purpose of embracing the pin which is to he removed. 10
